Beschreibung
Zusammenfassung:	The invention discloses a friction stir deposition repair method based on a hierarchical interface structure, which comprises the following steps: milling a V-shaped repair interface structure on a numerical control machine tool for surface irregular groove defects, milling a U-shaped repair interface structure for irregular pit defects, and milling a U-shaped repair interface structure for irregular surface impact through hole defects. And milling to form a through hole repairing interface structure. According to the principle of the friction stir deposition additive manufacturing technology, in the deposition additive manufacturing process, materials are not melted, the materials are heated to be softened and flow under the friction and stirring effects, and interface bonding coexists through metallurgical bonding and micromechanical interlocking. According to the characteristics of the technology, original irregular defects on the surface of the aluminum alloy are subjected to regular homogenization treatm
